Abstract
Description
Technical Field
[0001] This utility model relates to the field of cosmetic bottle technology, specifically a dual-chamber cosmetic bottle. Background Technology
[0002] A dual-chamber cosmetic bottle is a cosmetic packaging container with two independent storage chambers. Its core design lies in the physical separation structure that allows two or more cosmetic ingredients with different ingredients, textures, or functions to be stored separately in the two chambers. When in use, a specific release mechanism can be used to allow for independent retrieval from a single chamber or mixed retrieval of the contents from both chambers.
[0003] Cosmetic materials in different forms have different usage methods and sealing requirements. For example, cream or emulsion materials usually require the use of a dipping tool. However, if the dipping tool is exposed or not properly sealed to the material storage cavity, it is easy for the material to evaporate and become contaminated, affecting the effect and shelf life. Liquid materials are mostly dispensed by squeezing. If the sealing structure is not designed properly, leakage is likely to occur during carrying or storage, causing waste and inconvenience. In view of this, we propose a dual-chamber storage cosmetic bottle. Utility Model Content
[0004] The purpose of this invention is to provide a dual-chamber cosmetic bottle to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A dual-chamber cosmetic bottle, comprising: The bottle body has a first cavity and a second cavity inside. A dipping brush is provided in the first cavity, and the outer side wall of the dipping brush is in contact with the inner side wall of the first cavity. A nozzle is provided below the second cavity. The top surface of the nozzle is fixedly connected to the bottom end of the bottle body, and the interior of the nozzle is connected to the interior of the second cavity. A bottle reinforcement component, which is disposed inside the bottle body and is used to enhance the strength of the bottle body.
[0006] Preferably, the bottle reinforcement component includes a first reinforcement layer disposed inside the bottle body, a second reinforcement layer disposed inside the first reinforcement layer, and a third reinforcement layer disposed inside the second reinforcement layer, wherein the first reinforcement layer, the second reinforcement layer and the third reinforcement layer are bonded together with adhesive.
[0007] Preferably, the first reinforcing layer is made of acrylic material and has a thickness of 0.1mm to 0.5mm; the second reinforcing layer is made of PET polyethylene terephthalate material and has a thickness of 0.2mm to 0.3mm; and the third reinforcing layer is made of PP polypropylene material and has a thickness of 0.1mm to 0.3mm.
[0008] Preferably, a fixing frame is fixedly installed at the top of the bottle body, the fixing frame is connected to the interior of the first cavity, a connecting frame is movably installed inside the fixing frame, and the bottom surface of the connecting frame is fixedly connected to the top of the dipping brush.
[0009] Preferably, the top outer wall of the bottle body is provided with a first thread, a top cover is provided above the connecting frame, a fixing block is fixedly installed on the inner top surface of the top cover, the bottom surface of the fixing block is fixedly connected to the top surface of the connecting frame, and a third thread is provided on the inner side wall of the top cover, the third thread engaging with the first thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This dual-chamber cosmetic bottle has a first cavity and a second cavity inside the bottle body, each used to store different types of cosmetic materials. When the material in the first cavity needs to be used, the top cap is unscrewed via a first threaded engagement structure with the top of the bottle body. The top cap, along with a connecting bracket and a dipping brush, is then removed from the first cavity. The dipping brush can directly pick up the material from the cavity for use. After use, the top cap is screwed back on in the opposite direction, and the dipping brush returns to the first cavity, its outer wall contacting the inner wall of the first cavity to reduce material evaporation. For the material in the second cavity, the bottom cap is unscrewed, and the bottom cap is connected to the bottom of the bottle body via a fourth thread. The second thread of the bottle is separated, exposing the nozzle that was originally sealed by the plug inside the bottom cap. By squeezing the bottle body, the material in the second cavity can be squeezed out through the nozzle. After use, tighten the bottom cap, and the plug is re-attached to the bottom of the nozzle to achieve a seal and prevent material leakage. The first, second, and third reinforcing layers are bonded together with adhesive. The first reinforcing layer is made of acrylic, the second is made of PET, and the third is made of PP. This enhances the strength of the bottle body and prevents deformation during squeezing or collision. The anti-slip texture on the outside of the top and bottom caps increases the friction when unscrewing or tightening, making it easier to operate. Attached Figure Description

The interior of the nozzle 9 is connected to the interior of the second cavity 3. A bottle reinforcement assembly is installed inside the bottle body 1 to enhance its strength. The first cavity 2 and the second cavity 3 inside the bottle body 1 are used to store different types of cosmetic materials. When the material in the first cavity 2 needs to be used, the top cap 4 is unscrewed through the engagement structure between the top cap 4 and the first thread 7 on the top of the bottle body 1. The top cap 4 then pulls the connecting bracket 12 and the dipping brush 10 out of the first cavity 2. The dipping brush 10 can directly dip into the material in the cavity for use. After use, the top cap 4 is screwed back on in the opposite direction, and the dipping brush 10 returns to its original position. The outer wall of the first cavity 2 contacts the inner wall of the first cavity 2, which can reduce material evaporation. For the material in the second cavity 3, when in use, unscrew the bottom cap 5. The bottom cap 5 is separated from the second thread 8 at the bottom of the bottle body 1 through the fourth thread 14. The nozzle 9, which was originally sealed by the block 15 inside the bottom cap 5, is exposed. By squeezing the bottle body 1, the material in the second cavity 3 can be squeezed out through the nozzle 9. After use, tighten the bottom cap 5, and the block 15 is re-fitted onto the bottom end of the nozzle 9 to achieve a seal and prevent material leakage. The first reinforcing layer 16, the second reinforcing layer 17 and the third reinforcing layer 18 are bonded together with glue. The first reinforcing layer 16 is made of acrylic material, the second reinforcing layer 17 is made of PET material and the third reinforcing layer 18 is made of PP material, which can enhance the strength of the bottle body 1 and prevent deformation when squeezed or collided. The anti-slip texture on the outer side of the top cap 4 and the bottom cap 5 increases the friction when unscrewing or tightening, making it easy to operate.
[0019] In this embodiment, the bottle reinforcement component includes a first reinforcement layer 16, which is disposed inside the bottle body 1. A second reinforcement layer 17 is disposed inside the first reinforcement layer 16, and a third reinforcement layer 18 is disposed inside the second reinforcement layer 17. The first reinforcement layer 16, the second reinforcement layer 17, and the third reinforcement layer 18 are bonded together with adhesive. The first reinforcement layer 16 is made of acrylic, the second reinforcement layer 17 is made of PET, and the third reinforcement layer 18 is made of PP. This enhances the strength of the bottle body 1 and prevents deformation during compression or collision.
[0020] In this embodiment, the first reinforcing layer 16 is made of acrylic material and has a thickness of 0.1mm to 0.5mm. The second reinforcing layer 17 is made of PET polyethylene terephthalate material and has a thickness of 0.2mm to 0.3mm. The third reinforcing layer 18 is made of PP polypropylene material and has a thickness of 0.1mm to 0.3mm. The first reinforcing layer 16, the second reinforcing layer 17, and the third reinforcing layer 18 are bonded together with adhesive. The first reinforcing layer 16 is made of acrylic material, the second reinforcing layer 17 is made of PET material, and the third reinforcing layer 18 is made of PP material, which can enhance the strength of the bottle body 1 and prevent deformation during squeezing or collision.
[0021] In this embodiment, a fixing frame 6 is fixedly installed on the top of the bottle body 1. The fixing frame 6 is connected to the interior of the first cavity 2. A connecting frame 12 is movably installed inside the fixing frame 6. The bottom surface of the connecting frame 12 is fixedly connected to the top of the dipping brush 10. When the material in the first cavity 2 needs to be used, the top cover 4 is unscrewed through the engagement structure between the top cover 4 and the first thread 7 on the top of the bottle body 1. The top cover 4 drives the connecting frame 12 and the dipping brush 10 to be taken out from the first cavity 2. The dipping brush 10 can directly dip into the material in the cavity for use.
[0022] In this embodiment, the top outer wall of the bottle body 1 is provided with a first thread 7, and a top cover 4 is provided above the connecting frame 12. A fixing block 11 is fixedly installed on the inner top surface of the top cover 4. The bottom surface of the fixing block 11 is fixedly connected to the top surface of the connecting frame 12. The inner side wall of the top cover 4 is provided with a third thread 13, which meshes with the first thread 7. After use, the top cover 4 is screwed in the reverse direction and the dipping brush 10 returns to the first cavity 2. Its outer side wall contacts the inner side wall of the first cavity 2, which can reduce the volatilization of materials.
[0023] In this embodiment, the bottom outer wall of the bottle body 1 is provided with a second thread 8, and a bottom cover 5 is provided below the nozzle 9. The inner wall of the bottom cover 5 is provided with a fourth thread 14, which engages with the second thread 8. When using the material in the second cavity 3, the bottom cover 5 is unscrewed, and the bottom cover 5 is separated from the second thread 8 at the bottom of the bottle body 1 through the fourth thread 14. The nozzle 9, which was originally sealed by the blocking block 15 inside the bottom cover 5, is exposed. By squeezing the bottle body 1, the material in the second cavity 3 can be squeezed out through the nozzle 9. After use, the bottom cover 5 is tightened, and the blocking block 15 is re-attached to the bottom end of the nozzle 9 to achieve a seal and prevent material leakage.
[0024] In this embodiment, a blocking block 15 is fixedly installed on the inner bottom surface of the bottom cover 5. The blocking block 15 is sleeved with the bottom end of the nozzle 9. The blocking block 15 is re-sleeved onto the bottom end of the nozzle 9 to achieve a seal and prevent material leakage.
[0025] In this embodiment, the outer walls of the top cover 4 and the bottom cover 5 are provided with anti-slip textures. The anti-slip textures on the outer sides of the top cover 4 and the bottom cover 5 increase the friction when unscrewing or tightening, making it easier to operate.
[0026] In this embodiment, a dual-cavity cosmetic bottle is used where the first cavity 2 and the second cavity 3 inside the bottle body 1 are used to store different types of cosmetic materials. When the material in the first cavity 2 needs to be used, the top cap 4 is unscrewed through the engagement structure between the top cap 4 and the first thread 7 on the top of the bottle body 1. The top cap 4 drives the connecting bracket 12 and the dipping brush 10 out of the first cavity 2. The dipping brush 10 can directly dip into the material in the cavity for use. After use, the top cap 4 is screwed back on in the opposite direction, and the dipping brush 10 returns to the first cavity 2, with its outer side wall contacting the inner side wall of the first cavity 2, which can reduce material evaporation. For the material in the second cavity 3, the bottom cap 5 is unscrewed when used. The bottom cap 5 is connected by the fourth thread 14. Separated from the second thread 8 at the bottom of the bottle body 1, the nozzle 9, which was originally sealed by the block 15 inside the bottom cap 5, is exposed. By squeezing the bottle body 1, the material in the second cavity 3 can be squeezed out through the nozzle 9. After use, the bottom cap 5 is tightened, and the block 15 is re-attached to the bottom of the nozzle 9 to achieve a seal and prevent material leakage. The first reinforcing layer 16, the second reinforcing layer 17, and the third reinforcing layer 18 are bonded together with adhesive. The first reinforcing layer 16 is made of acrylic, the second reinforcing layer 17 is made of PET, and the third reinforcing layer 18 is made of PP. This can enhance the strength of the bottle body 1 and prevent deformation when squeezed or impacted. The anti-slip texture on the outside of the top cap 4 and the bottom cap 5 increases the friction when unscrewing or tightening, making it easier to operate.
